A non-invasive way to monitor blood sugar could help millions of diabetics check their condition without drawing blood. Princeton Professor Claire Gmachl is developing a technology to do just that, using a laser to measure blood sugar through the skin. It is one of many research projects at Princeton University that have the potential to benefit society.
The video below highlights three researchers who are striving to improve people's lives through innovations in science and engineering. Like most Princeton researchers, the three faculty members and their teams are strongly motivated to apply their discoveries to solving real-world problems.
